BFE is a Layer 7 HTTP and HTTPS traffic distributor that routes requests based on content inspection and configurable policies, managed through a RESTful API. It operates as a reverse proxy, distributing incoming traffic across backend servers according to user-defined rules.
The project distinguishes itself through a domain-specific language for content-aware routing, allowing traffic to be directed by inspecting request headers, paths, and payloads. It supports multiple configurable load balancing policies and includes a plugin-based extension system for adding custom modules and middleware without modifying core code. Backend health monitoring tracks service status and performance using built-in metrics.
Configuration and routing rules are managed programmatically through a centralized REST API and dashboard interface. The plugin framework enables rapid development and integration of custom load balancing features.
